SyntaxError: invalid syntax

Process finished with exit code 1

我进行了转码但是还是不行这是为什么啊

1. 老师,这个是在哪在pycharm

2. 还是得下载软件呢

   
   

老师，您看这是什么错误，怎么解决呀？？？

老师，这个课程中的包chaojiying_Python没法安装呢

老师，为什么urllib最新版4下载不了，点进去就一直是加载状态

这个是怎么回事 已经安装了这个库啊

能不能把爬虫和其他所有的文档改成高淇老师的那种文档，PDF格式，看起来非常清晰的？？？？？？

这里每次运行request一次就会自动扣费吗

老师我搞错了，没事了，这个是要下载python开发代码导入模块

老师，本阶段资料下载  里面没有MongoDB的文档呢，可以分享一下吗？

老师，这是结果报的是NoneType: None，应该怎么办啊

老师，我一直有一个问题，不知道到底是什么原因，在这个爬虫视频教程中视频老师一共用了三次“cookies”
跳过密码登录；但是我为什么不行，我把登录后的网址复制到scrapy中，然后直接访问网址；
它不会报没有登录，请登录这个错误。而是把源代码直接打印出来，但是打印出来的源代码又不是
我复制的这个登录后的源代码，而是登录前的源代码；我换很多网址和账号，都不知道到底是为什么；

老师，就像这个，这是我大学学校的一个学习网址。我粘贴的这个网址(

http://trzy.edu.chinaacc.com/student/mycenter/wdzl.shtm

)是登录到我的账号信息里面去了的；可是我直接这样访问网址它居然不像视频中老师那样显示没有登录，请登录这样的话；二就是直接打印源代码，而这个源代码又根本就不是我这个网址当前的源代码；   从我们爬虫基础到scrapy到现在高级，一共用cookies跳过密码登录三次，但是每一次我都是报这个错误；希望老师你帮忙看一下，我实在不知道是什么原因；一直纠结个很长时间，这个查百度也都无法查
